PERMUIATION-SWITCH.

Application led April 29, 1919.

l VTo all whom t may concern:

Be itlrnown vthat I, SAMUEL R. SENSE, a citizen of the United IStates,residing at Vanderbilt, in the county of Fayette and State ofPennsylvania, have invented certain new and useful Improvements in.Permutation-Switches, of which the following is a specication.

My invention relates to a `permutation switch adapted to beinstalledupon automobiles or the engine thereof to prevent the unauthorizedoperation of the automobile.

An important obj ect of the invention is to provide a device of theabove-mentionedl character, which is formed of few and cular support 16,which is formed of insimple parts, and which may be easily andconveniently operated when the combination is known. l

Av further object of` the invention is to provide a device of theabove-mentioned character which may be'easily operated for opening andvclosing, the circuit, if desired, without working the completecombination.

Other objects and advantages of the invention will be apparent duringthe course of the fol-'lowing description.

In the accompanying drawings forming a part of this specification and inwhich like numerals are employed to designate like parts throughout thesame:

Figure 1 is an elevation of the front face of the device;

Fig. 2 is a side elevation of the device;

Serial No'. 293,509.

Fig. 10 is a perspective view of a leaf .Springs and,

Fig. 11 is a perspective view of the contact arms. l

In the drawings, wherein for the purpose of illustration is shown apreferred embodi- 'ment of my invention,'the numeral 10 designates' acasing, fitted within an openingV 11, formed in a dash 12. This casingis pro- *vided at one end with a iange 13, adapted to engage with a dial14,'these parts being held together by screws 15, passing through thedash 12 and preferably having their heads arranged at the rear of thisdash.

Arranged within the casing 10 is a cirsulated material. This support issecured to the casing 10 by screws 17 or the like.

Upon the forward side of the insulated support 16 is arranged an annularcontrol member or rack 18, crimped for providing depressions orv notches19. This annular control member comprises stationary contact elements 20andl 20thoroughly insulated from the other portions of the'controlmember. These stationary contacts are vconnected with binding posts orscrews 21, connested with wires 22, included in the ignition circuit,one of these wires passing through an opening 23. The lrear end of thecasing V1() is closed, as shownv at 24, and this closed end is equippedwith a tube 25, which may receive one wire 22. The stationary contacts20 and 20 are arranged opposite each other, as shown in Fig. 4.

The numeral 21 designates an operating shaft or element, formed insections 22 'and 23', which are. rigidly connected and thoroughlyinsulated from each other. As shown in Fig. 7, the section 22 isprovided with a longitudinal groove 24', while the section 23 Vcarriesan extension or tongue 25a, projecting into this groove. Screws-25engage with portions of the section 22 and vpass through openings 26,insulating ma- 4forwardly of the shoulder is a. portion 29,

which is square in cross section. Forwardly of the square portion 29visa reduced portion 30, circular in cross section, and carrying a head 31,separated therefrom and clamped thereto by a set screw 32. The circularportion 30 is slidably mounted within an opening 33 formed in theinsulatin support 16.

he numerals 34 and 35 designate contact arms, the outer ends of whichcarry curved elements 36, to lit in the notches or depressions 19. Thestationary contact elements 20 and 20 forming in e'ect a continuation ofthe control member 18, prevent the combination from being ascertained bythe travel of the contact arms over the control member. The contact arm34 is provided at its inner end with a head 37, having a circularopening 38 formed therein, rotatably receiving the square portion 29,whereby this contact arm is rotatable upon the square portion. Thecontact arm 35 is provided at its inner end with a head 39 provided witha square opening 40 receiving the square portion 29, whereby the contactarm 35 is locked to the shaft 21 for rotation therewith. At their innerends the contact arms 34 and 35 are provided withangularly arrangedspaced shoulders 41 and 42, adapted to be moved into and out of contactwith each other, as shown. The numeral 42 designates a leaf spring,which is secured to the central portion of the support 16 by screws 43',and the free end of this spring is slotted, as shown at 44', to receivethe circular portion 30, and to engage beneath the head 31.

The dial 14 is provided with an annular scale 43, shown in Fig. 1, and apointer 44 is adapted to travel in proximity to this scale. This pointeris secured to a radially extending handle or knob 45 carried by theshaft 22', and serves to turn the same. The pointer 44 and the contactarm 35 extend in the same direction and remain parallel.

The point a on the scale 43 indicates the location of the stationarycontact 20, and the point b the location of the stationary contactelement 20', while these contact elements may be arranged in otherpositions. The points c and d indicate the extent of travel of theContact arm 35 with relation to the contact arm 34` moving in eitherdirection when said contact arm 34 is in engagement with the contactelement 20. To close the switch the pointer 44 is first shifted to thepoint b which would bring the contact arm 35 into engagement with thecontact segment 20', and then the pointer is advanced to the point ci,which is necessary to advance the contact arm 34 into engagement withthe stationary contact arm 20. The contact arm 35 now disengages thecontact element 20 and the pointer is swung into an opposite directionso that it is returned to the point I) whereby the contact arm 35engages the contact element 20. The circuit will now be closed as isobvious. If it should be desired to open the circuit without working theentire combination to again close it, the contact arm 35 may be swung ineither direction from the point b between the points c and d. When theshaft 22 is rotated, the spring 42 will normally hold the contact arms34 and 35 in proper engagement with the control member 18 but willpermit of slight reciprocatory movements of the shaft' to allow thecontact arms to trip over the control member.

It is to be understood that the form of my invention .herewith shown anddescribed is to be taken as the preferred example of the same, and thatvarious changes in the shape, size and arrangement of parts mayberesortedto without departing from the spirit of the invention or thescope of the subjoined claims.

Having thus described my invention, I claim:

1. A permutation switch of the character described, comprising asupport, an annular control member carried by the support and providedwith notches and including insulated contact elements, contact armsarranged to travel in proximity to the control mem ber and to engagewith the same, spaced shoulders carried by the inner ends of the contactarms, an element connected with one arm to turn it so that the shoulderof such arm engages the shoulder of the other contact arm to advance theother contact arm, and means for indicating the extent of movement ofthe arms.

2. A permutation switchof the character described, comprising a support,a curved control member carried by the support and provided with notchesand including spaced insulated stationary contacts, contactV armsarranged to travel in proximity to the curved control member to engagethe same, means whereby Vone contact arm may be swungl a restricteddistance with relation to the other contact arm and will then serve toswing such other contact arm, means to turn the first named contact arm,and means for indicating the extent of movement of the first namedcontact arm.

3. A permutation switch of the character described, comprising asupport, a curved control member carried by the support and providedwith notches and including spaced insulated stationary contacts, acontact arm to travel in engagement with the control member and providedat its inner end with an opening which is polygonal in cross sec-- tion,a coacting contact arm to engage the control member and provided at itsinner end with an opening which is circular in cross,

section, an operating shaft pivotally oonnected with the support andprovided With a portion which is polygonal in cross section, suchportion passing through the polygonal and circular openings of theoontact arms7 shoulders carried by the -inner portions of the Contactarms and normally spaced, a dial having a scale, and a pointer connectedwith the operating shaft and traveling in proximity to the scale.

In testimony whereof I afix my signature in presence of two Witnesses.
